There is no "Paxinos" atlas in NMT2, as far as I know. The NMT installation script includes the NMT2 template and the CHARM atlases for now. It will soon integrate the SARM subcortical atlas too (Paxinos was a coauthor of that) that is available separately here:

Let me know if that helps or if you need something else.
